The drama is a Korean, modern retelling of the 'Journey to the West' story, with Lee Seung Gi transforming into the role of Sun Wukong or Son Oh Gong. In his teaser clip, he describes himself as the "decadent fiend spirit". In Cha Seung Won's teaser clip, he describes himself as "the god of demons, the bull demon king".

Oh Yeon Seo, sporting a polka-dotted yellow umbrella with a written charm hidden on the inside, says, "I am a human who can see demons. I am the monk."

Curious about how these three trouble makers will come together? You can catch the premiere of 'Hwayugi' this December 23 at 9PM KST!
